SOLUTION
The formula for the equation of a line is,
![y=mx+b](https://img.qammunity.org/2023/formulas/mathematics/high-school/smsb8cbft03lwblmi49nf2l6jby2ofxzws.png)
From the question, we are to multiply the value of x by 3.
Therefore,
![m=3](https://img.qammunity.org/2023/formulas/mathematics/high-school/n9d8a7zx3khblupd8qiobmi8t4qlm66snp.png)
Which will then give us,
![y=3x](https://img.qammunity.org/2023/formulas/mathematics/high-school/x3q8kt3l366jfmm89tfr8zil9wuf8fwkg6.png)
And finally, we are to subtract 6 from the result to get the value of y
Therefore,
![b=-6](https://img.qammunity.org/2023/formulas/mathematics/high-school/1ftpq2eqxl0z0q21yu04amxapq7utxo1fx.png)
Which will become,
![y=3x-6](https://img.qammunity.org/2023/formulas/mathematics/college/3bfx64bxsnp3v4icitmuw2192ciligpq3q.png)
Hence, the equation in terms of x and y is
![y=3x-6](https://img.qammunity.org/2023/formulas/mathematics/college/3bfx64bxsnp3v4icitmuw2192ciligpq3q.png)
Therefore, the graph of the function is
